Navigate your entire federated schema without leaving Cosmo

Click through types, jump to any type with Cmd/Ctrl+K, and see real usage data for every field — all in one interactive view.

Built into Cosmo Studio. No external tooling required.

The problem

Federated schemas are hard to read

A composed federated schema is large and interconnected. Raw SDL gives you no usage data, no interactive navigation, and no way to see authorization requirements at a glance.

Raw SDL files are hard to navigate

A federated schema can span thousands of lines across multiple subgraphs. Finding a specific type or understanding its relationships requires text search and cross-file jumping.

Field usage is invisible without dedicated tooling

Teams cannot tell which fields clients actually query. Decisions about deprecation and removal are guesswork without usage data.

Authentication requirements are scattered

Knowing which fields require @authenticated or specific scopes means reading the schema definition line by line. There is no aggregated view.

Our solution

Interactive schema navigation with live usage data

The Schema Explorer renders the composed federated schema as a clickable UI. Navigate between types, search by name, and see real usage data from Cosmo analytics alongside every field definition.

From schema to insight

1. The Schema Explorer parses the composed federated schema and renders it as an interactive UI.
2. Click any type to navigate to it. Objects, interfaces, unions, enums, and inputs are all navigable.
3. The details panel shows all fields, arguments, and descriptions for the selected type.
4. Press Cmd/Ctrl+K to open the search modal and jump to any type by name.
5. Usage data — pulled from Cosmo analytics — appears alongside field definitions.
6. The deprecated fields view aggregates all deprecated fields across the schema in one place, with their usage metrics.

Click to navigate. Search to jump. Analytics to decide.

Before & After
